IMPROVEMENT VIN VALVES.

TO AALL WHOM IT MAY CONCERN: l

Be it known that we, ADAALGOOD, Jr., and SIMON STROUSE, of Titusville,in the county of Crawford, and State o'f Pennsylvania, have inventedcertain new and useful Improvements in Valves; and we do hereby declarethat the following is a full, clear, andexact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification, .inwhich- Figure 1 represents a view in section of our improvedunion-coupling and valve.

Figure 2, a view of the valve thereof, as seen from the bottom end.

Figure 3, a plan or top view of the valve-seat.

The nature of our invention consists in combining a valve for thepassage of steam, wateror other fluids with a union-coupling, forconnecting the receiving and delivery pipes through which the same isconducted, in such manner that risk of leakage through the valve is'obviated, and enabling the latter to be readily removed when desired,for the purpose of renewal or repair.

In the accompanying drawings, which show'a convenient arrangement ofparts for carrying out the objects of our invention, the union-couplingis represented as composed of two chambers, A A, t;r'the outer endsofwhich the receiving and delivery-pipes are screwed, and which are unitedbythe coupling-nut B. i

yA circular valve-seat, C, is inserted in the top of the chamber A,having a suitable ground-joint at'its junction therewith, and is held inposition by the chamber A, when the chambers A A are screwed together bythe coupling-nut B, the valve-seat resting against a shoulder in thechamber A. Openings c are made in lthe valve-seat for the passage of theHuid. vA. circular valve, D, moves longitudinally upon a stem or guide,

E, which is screwed into the seat C, and has a guard, e, upon its top,to prevent the valve from lifting too far from thefs'eat.

Vlhevalve-seat and stem areconcentric with -tlie chambers ADA. The valveD and seat C 'are faced accurately upon their meeting-surfaces, or, ifdeemed necessary, rubber or other packing may be interposed betweenthem.A When the valve is in contact with the scat, 'the openings c areclosed, and no fluid can pass from A to A'. A

It will be 'seen that wear of thevalve upon the stem will not have anytendeneyt produce leakage;

It is readily adaptable to use as a pump or check-valve, or any otherpurpose to which a-valve is applicable, obviating the use of a specialcage, and can easily be taken out for renewal or repair when desired.

In order to produce au intermitting motion of the valve, we .provide itsbase with recesses, iz', inclining or sloping in one direction.

What we claim, and desire to secure by Letters Patent, is p The valve D,provided with inclined or sloping recesses z', in combination with stemE, seat C, and c haml bers A A', all arranged to operate substantiallyas described.'

In testimony that we claim the foregoing as our own, we aix oursignatures in presence of two witnesses.
